Specification of Letters Patent.

Patented July 3, 1906.

Application filed September 9, 1904. Serial No. 223,877.

1'' 0 ail whom it may concern:

Be it known that we, JOHN S. DOAK, residing at Brownwood, Brown county,and AL- EXANDER G. FARRINGTON, residing at Yoakum, Lavaca county, Texas,citizens of the United States, have invented certain new and usefulImprovements in Insect-Destroying Machines, of which the following is aspecification.

This invention relates to machines for destroying insects from growingplants and the object is to improve the machine disclosed in our pendingapplication, filed April 11, 1904, Serial No. 202,649.

l/Ve have improved the means for gathering the insects by improving themanner of adjusting the troughs, hereinafter described, as to height. Ithas been found that in some fields the rid es on which the cotton growsare made higher than in other fields. The troughs must be elevated abovethese ridges. It has also been found that in fields where the cotton islarge the large or heavy bolls of cotton would drag through the troughsand would frequently dra the accumulated insects and squares an smallbolls from the troughs. It is as important to gather the squares andsmall bolls as it is to gather the insects, because the squares andsmall bolls contain the insects, particularly the insect known as theboll-weevil. Generally in cotton infested with boll-weevil thebollweevil causes the squares and small bolls to fall from thecotton-plants.

One object of our invention is to prevent the heavy bolls from dra gingthe insects and the squares and small b0 ls from the troughs. Otherobjects and advantages will be fully explained in the followingdescription.

Reference is had to the accompanying drawings, which form a part of thisapplication and specification.

Figure 1 is a perspective View of the machine from the rear, showing ascreen on one of the troughs. Fig. 2 is a cross-section of one of thetroughs. Fig. 3 is a detail view illustrating the adjusting-bar forelevating and lowering the sides of the troughs.

Similar characters of reference are used to indicate the same partsthroughout the several views.

Our machine is provided with a suitable truck composed of the archedaxle 1, the wheels 2 and 3, and the frame-pieces 3, 4, 5, 6, 7 and 8. Aseat 9 is mounted on the frame. Fig. 1 shows a rotary fan 10 and anagitator 11 for shaking the cotton-plants. The means for operating thelatter elements will not be described or claimed in this application,because they are described and claimed in our pending application. Thetroughs are suspended from the frame by sprin -arms 12 and by [chains13. Each troug 14 has an upwardly and outwardly extending wing 15, andeach trough is provided with a removable screen 16. Each screen is madeof a frame 17 and suitable wire attached to the frame. The mesh of thescreen is made large enough to let the insects and the squares and smallbolls fall into the troughs and yet large enough to prevent the heavybolls from dropping in the troughs and draggin the insects out. Thescreens are made easilyremovable, so that they can be taken out when notneeded. The troughs are provided with flexible strips 20 to prevent thebruising of the rowing plants. The frame of the screen is hinged to thetroughs by any suitable number of hinges 18. The troughs have a flange19 projecting inward from the inner edges. The trip 20 and the hinges 18are attached to the flanges 19 in the manner shown in Fig. 2 by bolts21. The screen is supported on the opposite side of the trough by aspring-catch 22, which may be riveted to the side of the trough.

The troughs are adjustable as to height by the chains 13 and by theadjusting-bars 23, which are attached to the axle by means of U-bolts24. The Wings 15 of the troughs are connected to the bars 23 by means oflinkrods 25, so that there will be a flexible connection. The U-boltsmay be moved up or down on the axle 1 for adjusting the sides of thetroughs up or down. The braces 26 are bolted to the bars 23 and areprovided with a presence ofltwo witne,'sses, this day of August, 1904.
